Question

write a Java program to calculate the value of given expression: 1/a^2+2/b^2+3/c^2​

Answer 1

import java.util.*;

public class expression

{

   public static void main(String[]args)

   {

       Scanner scan = new Scanner(System.in);

       double a,b,c;

       double value;

       System.out.print("Enter the value of a :");

       a=scan.nextDouble();

       System.out.print("Enter the value of b :");

       b=scan.nextDouble();

       System.out.print("Enter the value of c :");

       c=scan.nextDouble();

       value=1.0/(a*a)+2.0/(b*b)+3.0/(c*c);

       System.out.println("The value of the expression :"+value);

       scan.close();

   }

}

This is you program.
